PRODUCTIVITY FORMATION OF COMMON VETCH (VICIA SATIVA L.) IN A MIXTURE WITH WHITE MUSTARD

Abstract

The field experiment was conducted in 2024 on the farm of farmer E. Černius, located in the Kupiškis district. The two-factor experiment investigated how different seed rates and biological (bacterial) preparations affect the formation of seed vetch productivity. Factor A seed vetch seed rate: seed vetch 20 kg ha^-1 + white mustard 5 kg ha^-1; seed vetch 40 kg ha^-1 + white mustard 5 kg ha^-1; seed vetch 60 kg ha^-1 + white mustard 5 kg ha^-1; seed vetch 80 kg ha^-1+ white mustard 5 kg ha^-1; seed vetch 100 kg ha^-1+ white mustard 5 kg ha^-1. Factor B – use of biological preparation: not sprayed; sprayed 0.1 l/ha after germination (BBCH 12-19). Measurements of plant biometric indicators and yield structure elements were performed before harvest by measuring 10 plants at random locations of each variant by direct counting, measuring and weighing. Spraying with a biological preparation had an effect on plant height: in all variants, positive significant differences were determined between the same seed rate when the plants were sprayed with a biological preparation. The significantly highest number of seeds in the pod was determined both without using a biological preparation, when the seed rate was 40 kg ha^-1 - 8.7 pcs., and when the vetch seed rate was 80 kg ha^-1 and a biological preparation was used - 8.6 pcs. The biological preparation did not affect the higher yield of the vetch and mustard mixture. The significantly highest yield was determined when the vetch seed rate was 80 kg ha^-1and no biological preparation was used - 2.4 t ha^-1.
